And restriction, term " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected,
Or it is integrally connected；Can be mechanical connection or electrical connection；Can be joined directly together, intermediary can also be passed through
It is indirectly connected.For the ordinary skill in the art, it can understand above-mentioned term in the utility model with concrete condition
Concrete meaning.
As Figure 1-4, the spray pump valve described in the present embodiment, including sealing cup 1, valve chamber 2 and valve rod 3, valve chamber 2 seal
It is connected in the neck of the bottom centre of sealing cup 1, the bottom of valve rod 3 is arranged in valve chamber 2, and top is arranged on outside valve chamber 2, valve rod 3
Centered on set and use through hole 3a, through hole 3a bottom is plugged with control water bar 4, controls and is provided with the first spring between water bar 4 and valve chamber 2
5, piston 6 is socketed with valve rod 3, and second spring 7 is provided between piston 6 and valve rod 3, is provided between control water bar 4 and valve rod 3
For connecting through hole 3a and lower valve chamber 2a passage 8, control water bar 4, piston 6 are close in the presence of the first spring 5, second spring 7
Sealing-in is touched and closes passage 8.
It is provided with the lower valve chamber 2a of valve chamber 2 for limiting the spacing along 9 of the maximum amount of moving down of piston 6.
The bottom of valve chamber 2 is provided with feed tube 10, and the bottom of valve chamber 2 is additionally provided with ball sealer 11.
Steam vent 12 is provided with the side wall of valve chamber 2.
The bottom of control water bar 4 is provided with control water pond 4a, and some place's L-type raised lines are circumferentially uniformly provided with control water bar 4
